The device has a plurality of illumination units for illuminating the surface of the spatial light modulator; each unit comprises a focusing element, and a light means that emits sufficiently coherent light such that each of these illumination units illuminates one separate illuminated region of the surface, whereby the focusing element and the light means are arranged such that the light emitted by the light means coincides close to or at the observer eyes.

Description

Supplementary correction period: February 11, 2011 IX. Invention: [Technical field of invention] This is a three-dimensional scene of the large-area video hologram (10) j) that uses the f brain to generate a large-scale scene. (4) Fine-change 11 containing an electronic control unit (Electronical^(10)). The cells (Cells) can enter the coding, joint light_amplitude and/or phase of each unit according to the video full image value. At the 5th, the dynamic stereo display function, the reconstruction of the video hologram can also use the video display power b' to perform the conversion of the plane or stereoscopic scene.

In this paper, the scene described by CGH can be calculated from the scene data. CGH represents the amplitude and phase complex value of the ί wave, which is the w ϋΛ required to reconstruct the scene. Calculate the CGH value, such as by tracking the homology ray, stimulating the interference between the scene and the reference light, or by using the Fcmrie resne effect. , you can calculate. The Air Conditioner (SLM) adjusts the wavefront of the incident light. The ideal SLM can represent complex values, such as the phase of the control of the amplitude and phase of the light. However, a typical SLM can only control one characteristic of amplitude or phase, or it can have side effects that affect another characteristic. There are a number of methods that can be used to adjust the amplitude or phase of the light, such as liquid crystal SLM using electrical = address (electncally addressed), optical addressing (〇ptic liquid crystal SLM, micro-mirror or acousto-optic modulator). It can be contiguous or contain individual mosquito nets (10), which can be early or double-dimensional, multi-layer or continuous. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, In the content of this article, "魄 魄 ^ ^ , , , , , , , , , , , , , , , , , , , , , , ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ Compared with the function of autostereoscopic display, it can be seen that the stereoscopic scene uses the wavefront to perform the image, and the observer according to the invention, the reconstruction effect is extended. In a space, the eye and the spatial light modulator (10) are extended. The unit that is less than ΪΪίΓ/卜 is preferably a light-conducting permeable unit that can be imaged. This allows for a full-image reconstruction that interferes with the current modality of a few millimeters. The construction has a spatial dimension artifact. This type of light can be called "sufficient coherent light." The temporary storage of the required sentence is the same as the scheduling. The spectrum of the light emitted by the light source _ ' must be narrow enough to be limited to the range of the monochromatic wavelength, which is enough to ensure the holographic reconstruction. The bamboo shooting angle of the SLM is proportional to the wavelength, which means that the gas uses a single-color light source to reconstruct the fresh image of the object. The widened spectrum causes widened object points and blurs the reconstruction of the object scene. The spectrum of the laser source can be viewed as a monochromatic source. The spectral line width of the LED should be narrow enough to aid in the reconstruction of a good view. The space is related to the degree of laterality of the light source. Conventional light sources, such as LED or cold cathode fluorescent lamps, can also meet the requirements if they are transparent by a suitable narrow aperture. The light of the laser source can also be regarded as being within the diffraction range. The radiation of the light source point depends on the color saturation of the module, which can provide a vivid scene reconstruction of the object, such as the point of each object can be reconstructed into a scene point within the diffraction range. . The light from the coherent light source in space can be extended laterally, which can cause a blurred scene reconstruction effect. At a certain position, the 'reconstruction of the object point scene will widen the size' will cause blurring of the scene. In order to use the coherent light source for scene reconstruction in space, it is necessary to sacrifice brightness, and use 1351588.* * Supplementary correction date: February uday, 2011 An active aperture to limit the lateral extension of the light source. The smaller the light source, the better. A linear light source can be considered as a point source if it is viewed from a longitudinal extension _ straight angle. Light waves can therefore conduct coherent conduction in this direction, but produce homology in other directions. -a ' %

The same scheduling of space In general, scene reconstruction can be performed by overlapping light waves in the horizontal and vertical directions. The holographic image of this type is called a full parallax scene. If a sufficient window or observation area is provided, the reconstructed object contributes to the horizontal and vertical motion parallax, just like a real object. However, large observer windows require high resolution at both the horizontal and vertical directions of sij. SLM requirements are often limited to functionally limited views with only horizontal parallax _). It is only necessary to reconstruct the hologram in the horizontal direction, but it cannot be built in the vertical direction, which will cause the parallax of the motion of the reconstructed object in the horizontal direction, but not in the vertical direction. The ΗΡ0 scene has a poorer resolution in the SLM _ straight direction than the full parallax scene. Only the vertical parallax (10) can be obtained less frequently. The holographic reconstruction only occurs in the vertical direction, resulting in a reconstructed object with a direct motion parallax, and no parallax in the lateral direction. Different scene observation effects can be obtained in the left and right eyes respectively. Description of related art applications For example, the display function of spatial light modulator installed in the transmission and LCD technology can be used for scene coding and reconstruction. A well-known high-resolution conductive large-area scene reconstruction is known. m ' 巧巧靖 H can directly rely on her unit, - often used, relying on the county view $, Cai (four) can also be applied to the lighting system that produces the scene, can ignore the scene reconstruction ° the linear light source can Release the collimated light. The device is positioned on the focal plane of the cylindrical mirror and produces multiple layers of plane waves, ie 1351588. Supplementary correction date: The incident angle of February 11, 2011 is provided in light transmission mode. Unlike the point source, the hall and image can be displayed without the astigmatism installed. The file content of the ΓΓ5699 of the image is the display of the hologram: the content of the hologram can be reconstructed by partial scenes. The scene cocoa is coded on the 're-reflective imaging plane' under the H sub-"Cocoa two f (EASLM). The 3D object is used to observe the reconstructed content of all parts of the scene as an early scene reconstruction of the entire northern object. Content. Positive... Scenery can be set up with phase (4) and projection system, with a rectangular structure, on the plane, for example, can provide a fast synchronization structure with a sense of synchronization control = over the lions to make up the financial formula, π can let Part of the system is based on the county, so that the _ degree of riding needs to be at the correct reconstruction angle, and the picture::: ί is difficult. To avoid using large lenses as the reconstructed light for 70 pieces, it is recommended to use a lens array. The design of W〇2'044659 (US2006 Touch 5994) provided by Wenlin himself includes a stereoscopic image reconstruction technology including a dimming light, which is sorted according to single diffraction order = ί ίί=ϊϊ: i Let ί recreate the content without any interference, observe The window should be sufficient by the window, however, its size is measured by the second light source, and the other eye may be observed. If the position of the observer's eye is changed, the heart, (4), the heart == 2 inches, Cough jjca period: ζυιι牛 February u day, small is the size that can be viewed by the observer window. This phenomenon produces the effect of dimming the limbs and shrinks, and the sum of the existing SLM scenes is generated; Can achieve high quality "like the reconstruction of the inner Π 需 ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί Large Two other known shortcomings are insufficient illumination intensity for the SLM.

Solve the problem of this object, the existing scenes are customized, and then you can provide a three-dimensional surface to at least one observer, with the aim of the object and the spatial light modulator The light diffraction of the hghtmoduktorcells is carried out, and the image can be imaged in the two observed eyes. The video hologram information can be encoded at least. There are 2=video hologram or - megaphone full image, and time multiplex mode function, which can be used to display Beixun. The video hologram information includes the work of two spatial multiplex video holograms. 1351588 Supplementary amendment date: February 11, 2011, b, available at the same time The content of the parallax information lost by the eyes of each observer. According to the content of the present invention, the focusing mode is the use of multiple focusing elements. Under the common application of the specified light, the coherent light of (4) can be emitted, and the focusing elements are It can be composed of individual lighting units, which can use more lighting units, and at the same time, the illumination of the separated area on the surface of the spatial light modulator. The focus and the way of using light can be arranged for each lighting unit to make the lighting unit The light can provide at least one observer, and the virtual window near the eye is used. Each of the illumination units can use at least one extended video hologram to perform spatial light modulator local area coding ^ illumination. Turning over the area, it is necessary to reconstruct the complete stereoscopic image in front of the observer's eye with a flat-section geometry. The invention can indeed reduce the _ and weight of the device, and can also reduce the interference lens aberration while increasing the illumination intensity. The advantage of 'is that it can be used in different lighting units: multiple illumination sources in the light modulator' to increase the door's exaggeration: The interference can prevent multiple light source positions from being produced by dividing the surface of (4) Guangjing H into multiple regions, two =, = _ different adjustments can increase the force ^^ === of the light == light 1⁄4 The light source is arranged to form a line light source, or is arranged in a 线H 〇1歹 lenticular lens type parallel light line source. The light source of the light source provides sufficient scheduling in the direction of the light cylinder, so that only the source of the image is " reconstruction. This lighting feature supplements the date of correction: February 1st of the following year is limited to horizontal parallax and direct parallax, the scene table = the resulting video full image, only on the intersection line, but in the direction of the light source line: = like reconstruction only The positive and lost parallax that occurs in the line source can be reconstructed by multiple images. Need to get the sight information. The '7' of the dimension is arranged in a spatially spaced position. This Wei Ke Jiang Jian re-examines the outer side of the field of vision in the Applicant's above-mentioned patent by (off 00605_), that is, the p-blue table 诵 _27228 way, in the case of this ϊ = ί interval = the same observer In the replacement feature of the two video holograms, the ray bundles are superimposed on the near-vision quasi-ray beam, and the ray bundles are superimposed on the virtual window $ limited by the α~τ^Γ surface near the eye of the subject. The virtual window is located in the observations for scene reconstruction without interference. The interval A d (flot Diaphragms) can be located between the light and the focus of the illumination unit to achieve sufficient light source scheduling. The Fuming ΐ yuan towel, the light corresponding to the focus of the recording, is defined as the observation plane readable # (10) by the overlapping of the financial lighting unit to emit a bundle of light. Therefore, if the light shutter and the corresponding backlight line are used, the light of the observer's eye can be used to correspond to the light line, such as linearly arranging the light-transmitting elements such as the illumination shutter to find the observer window. Among the characteristics, the spatial light shutter and the corresponding backlight line can be replaced by LE-D devices that can be controlled by wave or organic organization. The device has a spot light cut-off area' and can be separated and activated, and the operation is similar to a line source. Lighting energy in this design. For example, the Slot Diaphragms design, the line source is the LED, which can provide enough __ degrees. This function can be used at high 11 1351588 ^ Ab ^ Λ -τ- ,, $ Supplementary amendment date: February 2, 2011

The Si Si Si 2 way provides better lighting. This function, such as the use of a scanning mirror to enter the two-beam scanning cat dispersion layer to achieve the position of the light spot, can be used as the focus of the light ^. The laser beam can produce any desired pulse on the incident surface, can be used to determine the overall angle Dispersing angle illumination of the dispersing surface. The advantage of the sweeping beam is that 'the right H is chosen to provide the appropriate surface. There is no light to allow the illuminating coffee to be tuned to the spatial light. The devices are arranged at a minimum interval, and the position thereof can be adjusted according to the present invention, and the short-focus distance of the poly-weight 1 and the full-size display of the full-size display can be used to accurately cover the display of the ice and the use of small-sized filaments. The recording will reduce the chromatic aberration by f, X ° b. 'Because of the short focal length characteristics of the focusing elements, the present invention separately performs light excitation. The arrangement of the focusing of each lighting unit, or the entire lighting unit becomes a single point source. In the known way, the observer's eye tracking is detected in a known manner, and the observer can view the displacement of the illumination line by the illumination device = the axis of the observer's eye To the position, such as the distance to the display, The distance to the photonic device on the light, or the focus of the optical focusing device, can be used to 'can also mix two devices at the same time. There are many different ways to use the focal length of the focusing device, known to use electro-fibrillation The liquid volume of the film changes, and the curvature is measured by the curvature = Mirror and then the osmotic distance _ section. This is also the meaning of the permeation column and the group. It can also be used to fine-tune the lens medium or the folding distance of the main medium. Liquid crystal materials can also be used in the operation. The refractive index can be controlled by the electric field in the light source arrangement characteristics described later. It can also be specified as the number of the work 3 lines 12 1351588 ^ Supplementary correction date: February 11, 2011 2 square 3^ silk The excitation can be performed by each of the focusing elements in the illumination unit. Such a longitudinal observer's eye, such as a shutter matrix illumination system of a backlight device, can be excited by a point source or a line source, and these broad eye positions are based on According to the content of the present invention, the changing position of the eye is provided in accordance with the present invention, and a more detailed description is given, that is, the thorn of the holographic image 4 is applied, but it is applied to the reconstruction of the color hologram. In a later case, the unit is In the prime position, it can be reconstructed according to the stereoscopic color to the color of the color, and these colors can be overlapped to allow the observer [embodiment] The detailed description of the present invention can display some details of the holographic display. Content. ^ The characteristics of these descriptions, that is, for a video hologram can also make a bribe reflection reflexor & it is best to make the device directly tuned to light, such as the Freederieksz unit. A better understanding of its device, that is, _ device features towel, that is, how to integrate the function of the image display with the use of a single parallax code, ., hall, and the reconstruction of the image. Use the space multiplex reconstruction function, please use it in the device of the patent towel W_6/Q27228 (this unit can be integrated with wire, lens and Wei automatic G5〇= piece. The image separation device, that is, the multiplexed scene between the two health centers, = knife separation = not belonging to the hair _ object. The image separation device is not shown in the description of the drawing. = Other methods can be used instead of the establishment of the multiplexed parallax scene, such as the function of the work. The characteristics of the device using time multiplex reconstruction are described in the content of the supplemental revision period: February 11, 2011, application W0 2004/044659 (US2006/055994). In the case of a video full image with a light wave overlap and coherence function, it is not affected by the lateral auto-standing and separation, and vice versa. A straight holographic reconstruction can satisfy the senses of the eye. The autostereoscopic scene separation and spatial multiplex function can produce the same viewpoint. <However, the present invention can also be used as a device for reconstructing a full-view video hologram. This device uses an illumination unit including a plurality of point light source matrices to align the lens device in a reasonable manner. The advantage of the present invention is that all of the illumination units do not require separate isolation between the individual point sources and their φ-specific lens bodies. Light rays near the lighting unit may have a small number of lens arrangements overlapping. Fig. 1 is a side elevational view showing three focusing elements 21, 22 and 23 when the cylindrical focusing lens is arranged in a lateral direction. The lateral source near vision quasi-beam (line source) LS2, which penetrates the focusing element 22 of the illumination unit, then enters the plane of observation, as exemplified. According to the present invention, a plurality of line light sources LSi, LS2, and LSa overlap each other, and the light rays radiated from the respective light sources provide sufficient scheduling in the straight direction and the lateral direction. The light. , will pass through the light transmission unit of the light modulator SLM. Under the action of the light modulator SLM f element, only the direct diffraction is performed, and the device contains the encoded image content. The focusing element 22 presents the image in a plurality of diffraction sequences using only _ useful sequence of sequences, and the line source LS2 observing the flat Φ OP. The beam emitted by the line source L&, according to the description, passes only the focusing element 22 of the focusing device 2. In Figure i, there are three beams showing the first diffraction sequence 4, the second diffraction sequence 5 and the negative one sequence 6. In the case of a single point source, the line source can produce a significantly higher illumination intensity. Multiple holographic regions with enhanced effects can be used, and in the case where each line of the 3D scene provides a line source, the illumination intensity can be effectively improved by reconstructing portions of the 3D-view. Another advantage is that it is not a function of laser light. It is placed behind the slotted diaphragm (sl〇t Diaphragms) in the arrangement of multiple conventional light sources. It can also be designed as part of the shutter, which produces enough Coherent light.

If the ray path is close to the spatial light modulator, the Fourier plane is equal to a plane containing the light source image.

Fresnel Conversion The Fresnel conversion can be used for spatial light modulators, the propagation of near-field light propagation. The wavefront can be represented by a spherical wave. The phase of the light wave is determined by the side coordinate value of the square of the value. Flat section The straight flat section is located between the observer window SLM and extends to the rear of the SLM. The scene can be reconstructed on this flat section. The size of the reconstructed scene is limited to this flat section, and is not limited by the periodic spacing of the SLM. Light device The light device can contain a coherent light source such as a laser or a partially tuned light source such as an LED. The temporary storage and spatial coherence functions of some coherent light source devices must be sufficient to help establish good scene reconstruction content, such as spectral linewidth and lateral extension of the radiating surface, which must be small enough. Observer Window (0W) The Observer window is the straight window on the viewing plane. This window allows you to see heavy 3D objects. 〇W is a F0Urier conversion of the scene and is located in a periodic interval to avoid seeing multiple images of object reconstruction. The size of (10) must be at least the size of the pupil. If at least one GW is located in front of the eye of the Weibo tracking system, the size of the MGW can be much smaller than the lateral extent of the observer's movement. This feature facilitates the use of an appropriate resolution SLM' and therefore has a small periodic interval. 〇w can be like a keyhole, through which you can see the reconstructed 3D object, you can assign 乂 0W to each eye, or both eyes. Periodic Interval 24 Supplementary Amendment Date: Φ 2 on February 11, 2011 shows that the distance 'P' containing the ten sides of the Addressable Cells is the spacing of the SLM single it. Reconstruction. Inter-light rugged code is used to reconstruct the distribution of light distribution. In most cases, the observation of the 'window in the window = the display of the building' is reflected in the scene. In particular, it must be reconstructed by the actual or operational stereoscopic light distribution, in the case of light distribution. The scene in space, which can contain multiple optical modulators (SLMs), can be used to modulate the incident wavefront of the line. The SLM can be used to display the amplitude and phase of the light of any arbitrarily distributed Na. However, the general necessary ΪΪίΐΡ phase single-variable measurement may not produce performance.
